The specifications say parallax adjustable from 25 yds to infinity.

My question is why would the scope be designed to remove parallax down to 25 yds? There’s only so much adjustment range on this scope and I find it maxes out somewhere around 300 yds for me. Wouldn’t it be better to have that limited adjustment range set farther out or am I missing something?

What is it about the scope design that creates such a limited adjustment range?

I also have a 16x SWFA and it has a huge adjustment range. I’ve adjusted parallax way out past 1000 yds and still have more adjustment to go.


I always check the low end parallax because I shoot airguns quite a bit. Short range parallax is important for very close range (10-50 yards) precision shots.

I called Leupold once about adjusting the parallax on a fixed AO scope and they told me I'd lose some parallax on the far side (past 100 yards if I recall). For airgun and many rimfire shooters 10-100 yards is the critical range for parallax adjustment and precision shooting.

I'm glad you brought this up however as I've been looking at the NF NXS line for my AR which I'd like to be able to take out to 300 yards or even a bit farther. Good info!
